DUST-COLLECTOR.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed February 14, 1918. Serial No. 217,124.

To all whom it may concern:

Be it known that I, FRANK A. MARASCIO, a subject of the King of Italy,residing at 'Phillipsburg,'in the county of Warren and State of NewJersey, have invented certain new and useful Improvements inDust-Collectors, of which the following is a specification.

My invent' on relates to apparatus for collecting the dust from shoe orleather finishing machines, in a manner whereby the same may be handledin a highly convenient and expeditious manner. 7

An important object of the invention is to provide apparatus of theabove mentioned character, formed offew and simple parts, and whichis'convenient to operate.

' Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a side elevation of the apparatus, showing thesame connectedwith a shoe or leather finishing machine,

Fig. 2 is a transverse sectional view taken on line 2 2 of Fig. 3, and,

Fig. 3 is a central longitudinal sectional view through the apparatus.

In .the drawings, wherein for the purpose of illustration is 'shown apreferred'embodiment of my invention, the numeral 5 designates a shoe orleather finishing machine as whole, including a horizontal shaft 6, theends of which are journaled in stationary bearings 7, secured to theupper ends of uprights 8. The shaft 6 receives its rotation from apulley 9, rigidly secured thereto, and rotated by any suitable means.Secured to the shaft 6 for rotation therewith are rolls 10, 11 and 12,having their peripheries covered with sand paper, emery paper or othergrinding or polishing material, adapted to grind or polish the soles ofshoes, particularly the edges of the soles. It is obvious that thegrinding action of these elements upon the leather produces a dust,containing fine particles of the leather and the grinding material, andfor this reason suction elements or nozzles 13 are arranged preferablybeneath the rolls and receive a portion thereof. These nozzles haveconnection with pipes 14, connected with a transverse pipe 15, havingconnection with a longitudinal pipe 16, which leads into the intake endof arotary blower or fan 17 This blower is driven by a pulley 18,engaged by a belt 19,

extending upwardly to engage a pulley 20,

rigidly secured to the shaft 6. Connected with the discharge end. of therotary blower or fan l'? is a pipe 21, which extends into the outer endof a coupling 22, included in my dust collecting apparatus. My apparatuscomprises a casing 23, formed of any suitable material, and having ahorizontal partition 24, which divides the same into. an upper chamber25 and a lower chamber 26, as clearly shown in Fig. 3.

The chamber 25 is closed by a door 25, While the chamber 26 is closed bya door 26, as shown.

The numeral 27 designates a horizontal V rotatable drum, preferablyformed of sheetv metal, and having its periphery provided of suitablesize, and which.

with apertures 28, are preferably. uniformly distributed over the'entire area thereof. The rotatable drum 27 is located in the forward,end of the chamber 26, as shown. Arranged inwardly of and at theforward end of the drum 27, is a head or ring 29, having an annularflange 31,

attached to the inner surwhich is rigidly face of the drum. The ring 29is provided at its inner edge with an annular flange 32,]

which is rotatable upon a stationar annular or tubular bearing 33,having a ange 34, rigidly attached to the end wall 35 of the casing 23.The end wall 35. has an opening 36 formed therein for the reception ofthe tubular coupling 22, which projects into the interior of thestationary annular bearing 33, as shown. At the .opposite end of thedrum, 27, and interiorly thereof, is disposed an imperforate head 37,provided at its periphery with an annular flange 38, rigidly attached tothe drum. From the foregolng description it'is obvious that the airladen with dust, enters one end of the drum, and

can only discharge therefrom through the apertures 28 in its periphery.

The head ,37 is provided centrally thereof with an opening 39, rod 40,the end of which is screwrthreaded, as shown at 41, but the opening 39is slightly larger than this screw threaded portion, and thereforepermits of the rod 40 being moved longitudinally thereof withoutscrew-threadfor the reception of a ed engagement therewith. The rod 40carries clamping nuts 42 upon the screw-threaded portion 41 thereof, andthese nuts serve to lock the rod 40 to the head 37 as is obvious. At itsfree end, the rod 40 has a reduced portion or tongue 43,'to enter alongitudinal opening-or groove 44, formed in the end of a horizontaldrive shaft 45, ournaled through stationary bearings 46 and 47. Thetongue and grooved portions of the rods 40 and 45 interfit to form ineffect a continuous rod, and the same is screw-threaded to receive asleeve or nut 48, which is adapted to span the tongue and groove,thereby securely locking the shafts 40 and 45 together. It is obviousthat by proper rotation of the sleeve 48, the same will travel to theright to uncover the tongue and groove portions, thereby enabling therod 40 to be disconnected from therod 45. When this disconnection iseffected the flange 32 may be removed from the annular bearing 33, andthe drum 27 removed from the chamber 26, to be cleaned or the like.

The lower portion of the drum 27 operates within a pan or receptacle 49,which is part1 or Wholly filled with water or other liqui to be appliedto the revolving drum. As clearly shown in Fig. 2, a guard-plate 50 issecured to the wall of the chamber 26 and arranged upon one side of thepan or receptacle 49, while a coacting guard-plate 51, is disposed nearthe opposite side of the pan, and is attached to the door 26. Thepurpose of these guard-plates is to prevent splashing of the water, bycentrifugal force, upon the sides of the chamber 26, and to return thewater into the pan. The pan 49 may be removed when the drum 27 isremoved.

The horizontal partition 24, separating chambers 25 and 26, has anopening 52, and this opening leads intoa vertical shell 53, provided atits lower end with a flange 54, rigidly attached to the horizontalpartition. The shell 53 has both ends open and holds a plurality ofperforated plates 55, arranged therein, as shown. The function of theseplates is to somewhat retard the discharge of air from the chamber 26,as this has been found advantageous, but the invention is in no senserestricted to thisoperation, as satisfactory results are obtainable bydispensing with these perforated plates. shell 53, the chamber 25 has anair outlet opening 56, leading to the atmosphere.

The shaft 45 is rotated by a pulley 57, engaged by abelt 58, engaging apulley 59, rigidly secured to a horizontal shaft 60, journaled throughbearin s 61. The shaft 60 carries a pulley 62, rigid y secured thereto,and this pulley 1s enga ed by a belt 63, engaging a pulley 64, rigi lysecured to a llOIlzontal shaft 65. This shaft is vjournaled through astationary bearing 66, and carrles a pulley 67, rigidly secured thereto,and en- Above the gaged by a belt 68, extending upwardly to engage apulley 69, rigidly secured to the shaft 6, to be driven thereby.

The operation of the apparatus is as follows:

The dust, consisting of fine particles of the. leather and the grindinmaterial from the rolls, is caught by the section nozzles 13, and passesthrough the several pipes to the intake end of the blower 17. The airladen With this dust is discharged through the pipe 21 and passes intothe rotating drum 27. This drum revolves in contact with the water inthe tray or pan 49, and its periphery is permanently covered with a filmof water, spanning the apertures thereof. As the air laden with dustpasses through these apertures, the dust contacts with the water and isthereby separated from theair, such water containing the dust beingreturned to the pan 49. After a suitable amount of the dust hasaccumulated in the tray and rotatable drum they may be removed forcleaning.

7 It is'to be understood that the form of my invention herewith shownand described is to be taken as a,preferred example of the same, andthat various changes in the'shape, size, and arrangement of parts mayberesorted to Without departing from the spirit of the invention or thescope of the subjoined claims. 1
